Carn Brea stands some 750 feet above sea level overlooking the towns of Camborne and Redruth. The castle itself is built on a granite outcrop and looks down upon Carn Brea village and the church of  St. Uny. A castle was recorded on the site as early as 1478 and the nearby monument visible for many miles around was erected in 1837 in honour of Lord De Dunstanville. Excavations have revealed that Carn Brea has been of great importance since Neolithic times with quantities of leaf-shaped arrow heads, axes and knives suggesting it was once an important trading centre. The Carn was extensively fortified and remains of Iron Age ramparts are still quite visible; many of the numerous entrances are intact. Legend tells of a giant named Bolster who would cross to the distant St. Agnes Beacon with a single stride and indeed an ancient well known as the giants well can be seen on the north side of the Carn.
